Claude Code Gateway

Overview

This is a response-limited version of the Sovereign Mind MCP Gateway, specifically designed for use with Claude Code on local machines. It prevents memory overload by automatically truncating large responses.

Key Features

• Response Size Limiting: Max 50KB per response (configurable)
• Row Limiting: Database queries limited to 100 rows by default
• Pagination Hints: Automatically adds hints when data is truncated
• Memory Safety: JSON serialization with overflow protection

Response Limits (Configurable)

Parameter	Default	Description
MAX_RESPONSE_BYTES	51200	Maximum response size in bytes
MAX_ROWS	100	Maximum rows from database queries
MAX_EMAIL_COUNT	25	Maximum emails per request
MAX_TASK_COUNT	50	Maximum Asana tasks per request
MAX_FILE_LIST	100	Maximum files in directory listings

Truncation Behavior

When responses exceed limits, the gateway:

1. Truncates the data to fit within limits
2. Adds _truncated: true to the response
3. Includes _original_count and _returned_count
4. Adds _message with pagination hints

Example truncated response:

{
  "success": true,
  "row_count": 100,
  "data": [...],
  "_truncated": true,
  "_original_count": 5000,
  "_returned_count": 100,
  "_message": "Results limited to 100 rows. Add LIMIT/OFFSET to query for pagination."
}

• v1.0.0 - Initial release with response limiting
